Hadyn Green said: "Just realised there are three time zones for the ceremony: Live on Sky, streaming with buffering delay, and then #Primeunderclass"

After the opening ceremony, Sky TV chief executive John Fellet reassured viewers they wouldn't miss important events on Prime. He admitted that by the end of the opening ceremony, Prime could no longer claim to be providing 'live' coverage.

He said that was to be expected with free-to-air television and any delays in the opening ceremony were because the event was so long.

It could be worse. US broadcaster NBC is sticking by its policy of delaying coverage until prime time for local viewers.
